Encode, Convert & Developer Tools

The small conversions and encodings that interrupt real work | Base64, URL-encoding, JSON that won't validate, a cron expression you can't quite read | done instantly in your browser.

Format and validate JSON, convert between JSON, YAML and CSV, decode a JWT, test a regular expression against live input, translate Unix permissions, or generate a QR code. Everything runs client-side, so you can paste sensitive payloads knowing nothing leaves the page. Developers, SREs and platform engineers keep these bookmarked for the dozen tiny tasks that would otherwise mean a scratch script or an untrusted online tool.
